LARD-PRESS AN D SAUSAGE-STUFFER.

SPECIFICATION forming part of Letters Patent No. 275,567, dated AprillO, 1883.

Application filed March 5,1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN G. BAKER, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented an Improved Lard-Press and Sausage-Stuifer, of which the following is a specification. My invention relates to a certain improvement in machines which can be used either for pressing lard or stuffin g sausages, an example of a machine of this class being that described in Letters Patent No. 179,757, granted to my assignees July 11, 1876; and my invention consists, mainly, of a safety device, fully described hereinafter, for preventing the breakage of the piston of the press-an accident which frequently occurs when the swinging frame has not been properly adjusted to its place prior to the depression of the piston into the cylinder of the press.

In the accompanying drawings, Figure 1 is a vertical section of the improved press; Fig. 2, a plan view, partly in section, and showing the frame, piston, screw, and operating mechanism moved away from the body of the press; Figs. 3 and 4, perspective views, drawn to an enlarged scalefor the better illustration of my ipvention; and Fig. 5, a section on the line 1 2,

A cast-iron cylinder, A, has in its closed bottom a recess, (1, communicating with a tubular spout, to which a tubular extension can be added when the machine has to be used for stuffing sausages. A perforated plate, D, by preference of cast-iron, is supported in the cylinder A at a short distance from the bottom of the same, and on this plate rests the lower edge of a perforated casing, E, between which and the inside of the vessel there is an annular space communicating with the space heneath the perforated plate D, the latter, as well as the perforated casin g, being removable from the vessel. To the interior of the perforated casing is adapted a'piston, F, attached to the lower end of a vertical screw, G, which passes freely through and is guided by the frame H, the thread of the screw being adapted to an internal thread in the hub of the bevel-wheel I, which gears into a pinion, J, on a shaft which has its bearing in the swinging frame, and which is provided with a suitable handle. The screw is prevented from turning in the present instance by'the usual key or feather adapted to a groove in the screw.

The above-described parts are substantially the same as those described in the aforesaid patent.

One end, m, of the swinging frame H is pivoted to 9. lug, n, on the cylinder A by a bolt, 19, which extends. through another lug, n, at the lower end of the cylinder, a rod, 10', passing through a lug, w, on the upper edge of the cylinder, and screwing into a lug, n, at the bottom of the same, the upper end of the rod forming a stud, t, projecting above the lug 'w, and having a head, q. j It is immaterial to the main feature of my invention how one end of the swinging frame is pivoted to the cylinder at one side of the same; but there must always be a headed stud, t, on the opposite side, whether it forms a part of the rod 1) or is separate therefrom.

The end m of the swinging frame is slotted, as shown in Fig. 5 and by dotted lines in Fig. 3, the slot being adapted to the stud t, and the head of the latter overlapping a portion of the end m of the frame, so that when the latter has been swung round it is locked vertically to the cylinder by the head of the stud.

One of the difficulties attending the careless operation of machines of this class has been the failure to properly adjust the swinging frame to the stud, so that on depressing the piston it was frequently brought into violent contact with the upper edge of the cylinder, and this has often resulted in the breaking of the piston. In order to prevent this difliculty, I loosely pivot to a pin, g, on the side of the lug w a turn-buckle, M, which can be retained in the position shown in Fig. 3, where it prevents the turning of the handle K, so that the piston cannot be depressed into the cylinder. The turn-buckle cannot be turned up so as to set the handle K at liberty until the slotted end m of the swinging frame has been prop erly adjusted to the stud t, when the turnbuckle may be adjusted to the position shown in Fig. 4, thereby locking the frame, setting the handle at liberty, and permitting the depression of the piston into the cylinder, but not before the former coincides with the latter. One side of the end m of the swinging frame comes into contact with a stop, 3

on theflange of the cylinder as said frame reaches a position where the coincidence of the piston with the cylinder is assured, and

when the frame is in this position the long 5 arm of the turn-buckle, when turned up, bears with such force against the end m as to be self-retaining in a vertical position, from which it cannot be turned without an effort, the bearing of the turn-buckle against the end m of 10 the frame also maintaining said frame in a properly-locked condition.

I claim as my invention-- 1. The combination of the cylinder A, its

stud t, and turn-buckle M with the swinging :5 arm having a slotted end, m, adapted to the stud, and carrying the piston F, handle K, and mechanism by which the piston is operated from the handle, all substantially as set forth.

2. The combination of the cylinder A, its stud t, and turn-buckle M with the swinging 2o arm having a slotted end, m, and with the stop y, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN G. BAKER.
